rendered useful. From the alteration or disorganization of 

 structure that takes place, there can little be done in the 

 chronic stage except careful shoeing, which the smith should 

 understand. 



PUMICED FOOT. 



This is called by horsemen a falling of the sole. It is pre- 

 ceded by founder, and is, in reality, one of the terminations 

 of that disease, arising from the slow, continued inflammation 

 of chronic founder, which causes absorption of the outer edge 

 of the coffin bone, the latter thereby gradually losing its con- 

 cave surface, and becomiug convex. The sole, yielding to 

 this gradual change, becomes flat, or, in some instances, con- 

 vex. Yery little can be done in such cases by way of treat- 

 ment ; yet by careful shoeing the animal may be rendered use- 

 ful, although never sound. 



CORINITIS. 



This is an inflammation of the coronary ligament, situated 

 ■within the upper part of the hoof and between the hoof and the 

 hair. This ligament secretes the horn forming the wall or 

 crust of the hoof, and when diseased ceases to perform its 

 function, or performs it very imperfectly ; as a consequence, 

 the coronet, or upper margin of the hoof, is contracted, which 

 causes the soft parts to bulge out in such a manner that it has 

 often been mistaken for ring-bone. This contraction often 

 causes lameness. The most frequent causes are, standing upon 

 plank floors, hard driving, and the neglect to apply softening 

 applications to the hoof. 



For treatment, apply a flaxseed poultice for several days, and
